AI activity cited as factor in July’s 0.4% UK GDP rise
The Office for National Statistics said the economy expanded by 0.4% month‑on‑month in July 2026, noting that AI‑related firms helped boost the services sector, though the exact contribution remains unclear.

UK gross domestic product grew 0.4% month‑on‑month in July 2026, beating the consensus forecast of zero growth among analysts (BBC Business). The Office for National Statistics (ONS) linked part of the surprise to activity from firms using artificial intelligence (AI), especially within the services sector.
ONS view on AI’s contribution
Liz McKeown, director of economic statistics at the ONS, said there was evidence that businesses involved with AI and related technologies helped boost the services sector not only in July but also in May and June. She added that many of the IT firms reporting the largest turnover “appear to be involved with AI”, while also acknowledging that quantifying the exact impact of AI is difficult.
Services sector and computer programming
The ONS highlighted services – and within that, computer programming – as the main driver of the July increase. The same BBC Business piece notes that the services‑sector performance was strong enough to lift overall growth above the zero‑growth expectation.
Company example: Ascendea
Rob Arnold, co‑founder of Ascendea, an AI‑focused firm that employs nine people, illustrated the productivity gains the ONS referred to. He said his company can develop applications for other businesses “100 times quicker at a 50th of the cost” because of AI. While Ascendea’s size is modest, the comment underscores the type of efficiency improvements that could translate into higher turnover for AI‑enabled IT firms.

Timeline of releases
- 11 September 2026 – ONS publishes July 2026 GDP figures (0.4% m/m) and comments on AI contribution.
- 11 September 2026 – BBC Business publishes an article linking the AI boom to the surprise growth.
Analysis of the evidence
The data confirm two points unequivocally: (1) the economy grew 0.4% month‑on‑month in July, and (2) the services sector, particularly computer programming, was the main source of that growth. The ONS’s qualitative observation that AI‑related activity helped boost the sector is supported by the quote from Liz McKeown and by the anecdote from Ascendea’s co‑founder.
What the evidence does not provide is a numeric share of GDP attributable to AI. The ONS explicitly states that it is “difficult to quantify the exact impact of AI”. Consequently, the claim that AI‑related businesses were the *key* driver accounting for the *bulk* of the services‑sector expansion overstates the available proof.
From an analyst’s perspective, the AI link is a signal rather than a measured driver. It suggests that AI‑enabled productivity gains are beginning to appear in turnover data for high‑growth IT firms, but the magnitude of the effect remains unknown. The modest size of Ascendea (nine employees) illustrates that the AI narrative is not limited to large incumbents; however, without firm‑level turnover figures, the aggregate impact cannot be isolated.
Implications for markets and policy
Investors tracking UK growth now have an additional narrative thread: AI activity may become a recurring factor in services‑sector performance. Yet, given the ONS’s caution, any forecasting that assumes AI will consistently deliver a measurable share of GDP should be tempered with the acknowledgement that the current evidence is qualitative.
Policymakers preparing the October budget may consider the ONS’s observation when designing support for AI research and adoption, but they should also recognise the measurement gap. Targeted surveys or firm‑level data collection could help quantify AI’s contribution in future releases.
What remains unknown
The ONS did not publish a breakdown of AI‑related turnover versus non‑AI turnover, nor did it provide a sector‑wide estimate of AI’s share of the services‑sector boost. The precise contribution of AI‑enabled firms to the 0.4% GDP rise therefore remains an open question.
Future releases that include more granular industry data or that track AI‑related investment flows could close this gap. Until then, the AI narrative should be presented as a contributory factor, not as the dominant driver of July’s growth.
